Does Isover's spacer sleeve provide an air gap (facade board)?

[hul]

Why are you including an installation where you have completely different conditions?
There are sheets that should be mounted with T-profiles. To make them airtight.

What do you mean by Husama?

What are the other conditions?
Can't you just answer why it is perforated?

 

[hul]

Research is conducted with ulterior motives. A company helps with its "knowledge".

So you don't trust any research because there is always someone behind it?

Of course, one should be critical of facts.
But when all studies show the same result. I've produced several without trying hard, and you haven't managed to come up with anything that supports your theories.

Doesn't that tell you something?

Already done

I have no theories. Just building facades that stand without any problems. Building facades on the west coast and facades in Norrland.

I follow what K-drawings tell me. During my years, I have never installed panels with crossed battens.

What do you mean by Husama then? I didn't understand the answer.

I asked why steel profiles were perforated and you only answered "Husama"
What do you mean by that?

 

[hul]

I have no theories. Just house facades that stand without any problems. House facades on the west coast and facades in Norrland.

I follow what the construction drawings tell me. In my years, I have never installed paneling with crossed battens.

But just because you haven't done it doesn't mean it's correct?
Advice and opinions change all the time, or do you build the same way you did when you started in the industry?

Can you answer what the other conditions are with facade boards/stone and steel profiles?

And why are they perforated?

There are different installations for façade panels. But the majority are mounted tightly against the batten (sometimes also with strip/band). A wooden panel does not become tight in the same way.

Facade panels can be mounted in different ways. But most are mounted tightly against the battens (sometimes even with a strip/list). A wooden panel does not become tight in the same way.

Yes, they are often mounted tightly against the battens. But the battens are always perforated.
My question is, why are they perforated?

I'll make it simple for you, why does the steel profile look like the attached image?

 

[SBH]

Yep, often mounted tight against the battens. But the battens are always perforated.
Why are they perforated is my question?

The boards are tight. Wood paneling is not tight.
The latest facade was with vertical battens and horizontal T-plates.

 

[hul]

The boards fit tightly. Wood paneling does not fit tightly. The latest facade was with vertical battens and horizontal T-plates

No, boards do not fit tightly, they are often mounted with a 5mm gap around the entire board against adjacent boards. So much more air comes in than what comes in through a wood panel.

How do you explain that?

 

[SBH]

No, boards do not end tightly; they are often mounted with a 5mm gap around the entire board against adjacent boards. So, significantly more air comes in than what comes in through a wood panel.

How do you explain that?

Are you thinking about this?

Are you thinking of this?

a bit hard to see your image writing over the mobile, but it probably fits.

but I think we drop this now, right?

Neither of us will obviously convince the other.
I hope I've opened the eyes for a few in the forum so if there's someone who wants to discuss further or just have a little help regarding building physics or similar, just write in the thread or PM.

Okay. You mount 4-6mm on a sealing strip. Which doesn't let in air

 

[GK100]

Didn't understand much in that post but I'll try to answer the little that was understandable, the rest you'll need to rephrase so we can try to answer.

Have we said that moisture doesn't transport in all directions?
The vertical battens are used to create the possibility for moisture to move in all directions and not be trapped.

How do you mean one has failed if a wide air gap is needed?
Two-stage sealed houses exist for a reason and there the wide air gap is an incredibly important part of two-stage sealed facades. Without it, the entire function disappears.

Don't pretend hul, hopefully nothing is unclear in that post to someone with your capacities. That you are playing with SBH in some sort of ring game may be the case but from my point of view, it looks extremely dull if not silly. I wrote earlier and now just to signal a bit that it isn't moving forward as you are carrying on.

It doesn't interest me enough and also doesn't add any value to the thread for me to join in this chatter. The only difference would be that it would soon crystallize into a significantly more fact-based direction where each party would directly have to show through their answers and rough calculations what they mean. And then some lab walls under conditions that can quite easily be questioned regarding their relevance in real-life walls won't help.

You can PM each other instead of all these short posts with little value at least for me as a reader. Yes, continue if you want, there’s nothing forcing me to read, but still.
